INTRODUCTION
The DigiReader Series is a family of Digital Proximity Readers (DigiReaders). (Graphic represen-
tations of the DigiReader Series —not to scale— are shown in figure 1, below, and figure 2, on page
5.) DigiReaders are bi-directional security devices that read digital credentials, (from either side of
the sensor), at ranges from 1 to 20 inches (2½ to 51 cm), depending upon the model and the
environmental conditions. DigiReaders are used with the NexSentry 4100, 4102, 4104, Star I and
Star II (4100 Series), SE818SC and SE422 Access Control Units (ACUs), with the ACUs either
operating as stand-alone devices or operating in conjunction with a StarGaze, a NexSentry Manager
(NSM), a NexSentry Command Center (NSCC), (an SE6000), or an SE5850, WSE Access Control
Host System. Connection between a DigiReader and an ACU is over the WSE proprietary S-Net
interface or over a Wiegand interface to a Wiegand ACU. (The Wiegand data can be either 26- or
34-bit Wiegand standard.) (Also included in the DigiReader Series is a keypad-only reader, the
DR4200K, which is the only family member available with the analog 818SX ACU.)
